To all whom it may concern:

Be it known that I, J o WALLACE J OHN- soN, a citizen of the United States, residing at Trenton, in the county of Grundy and State of Missouri,jhave invented a new and useful Hoisting Apparatus, of which the following is a specification.

This invention relates to that class of hoisting apparatus which is generally known as derricks, and among the objects of the invention are to provide a derrick of simple and efficient-construction which may be usefully employed for the purpose of raking or stacking hay and for the purpose of raisin or lifting heavy articles of all kinds, for the purpose of cleaning out wells, for quarry- Work, and, in fact, for all purposes for which hoisting apparatus of this'class is employed.

Other objects of the invention are to simplify and improve the construction and operation of this class of devices.

-With these and other ends in" view, which will readily appear as the nature of the invention isbetter understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being,. however, understood that no limitation is necessarily made to the recise structural details therein exhibited, but that changes, alterations, and modifications within the scope of the invention may be made when desired.

In the drawings, Figure 1 is a perspective view of a hay-derrick constructed in accordance with the principles of the invention. Fig. 2 is a vertical sectional view, enlarged, of the hoisting-drum and related parts. Fig. 3 isa perspective view showing a portion of the hoisting-lever and the means for connecting the hoisting-rope therewith. Fig. 4 is a corner by m ans/0f ang -Hens. which sectional detail view taken on the plane indicated by the line 4 4 in Fig. 2.

Corresponding parts in the several figures are indicated throughout by similar charac ters of reference. 7

The frame of the improved derrick includes a base or platform 1 and a top member or cap 2, said base or cap being preferably square, as shown, and connected at their latter are tilted or converged upwardly, the area' of the cap bein-g considerably smaller 4, having spindles 5 5, and an axle6, having spindles '7', is suitably secured upon two of the uprights or angle-irons 3'. Upon the spine. d'l'es of the axle 6 wheels 8 8'have been shown, and when the apparatus is to be transported similar wheels are to be mounted upon the spindles 5 of the axle 4. The derrickeframe may then be tilted so. as to be supported on the wheels, and it may then be. readily drawn from one place to another, as will be readily understood, a tongue or other draft attachwith. The cap member is provided at the in practice extended to the ground, where they may be staked or secured, thus assisting in securing the frame, structure. in an upright position for operation.

is a mast 11, which'may consist of ani 'on pipe of suitable dimensions, said mast being provided at its lower end with a sleeve 12, having an annular flange 13, which 1s supported upon antifriction-balls 14, which lat-. ter are disposed in'a ball-race 15 in the base, so that the mast will be capable of sw veling or oscillatory movement upon its axls. To,

stop member being supported in suitable bearings upon the base and adapted to. engage a notch 17 the flange 13; member 16 is actuated by means of a foot,- lever 18, which latter is suitably fulcrumed upon the base 1, L

The mast 11 is provided with a radiallyextending arm or bracket 19, upon the ex-. tremity of which is fulorumed the hoisting lever 20. Secured upon one side of the hoisting-lever is a clip 21 for the passage ofthe load-carrying rope 22, which latter 1s secured adjustably in the clip by means of a cam-lever 23, the toe or point of which is to compress, the latter within the clip 21.

The upper end of the mast 11 has a fork 24, with which is pivotally connected the hoist: ing-beam 25. The short end of this beam carries a loop or clevis 26, supporting a puls than that of the base. Transversely upon, the under side of thebase is mounted an axle.

rneIlt being conveniently connected there-v retain the mast stationary,- a slidable spring. I actuated stop member 16 is provided, sa d corners thereof witheyes with which guy- I ropes 10 are connected, sa1d guy-ropes being Supported centrally in the frame structure IOO adapted to engage the load-carrying rope and i ley or guide member 27. The long arm of the hoisting-beam carries a pulley or guide member 28, the load-carrying rope 22 being guided through a segmental slot 29 in the cap member 2 and over the guide-pulleys 27 and 28, the free end of said load-carrying rope being connected with the load that is to be lifted, which, in Fig. 1 of the drawings, has been illustrated as consisting of a hay fork or tongs 30 of ordinary construction.

The mast is provided above the cap 2 of the frame with a radially-extending arm carrying a pulley or guide member 32, over which passes a rope or flexible connecting member 33, one end of which is connected with the loop or clevis 26 at one end of the hoisting-beam, while the other end of said connecting member is connected with the hoisting-lever 20 by means of a clevis 34, suitably attached to said hoisting-lever.

Suitably connected with the sleeve 12 at the lower end of the mast is a frame 35, affording bearings for a shaft 36, upon which is secured a winding-drum 37. Connected with the frame is a yoke or bail 38, with which is securely connected one end of the hoisting-rope 39, which rope after being guided over the pulley 40, connected with the free end of the hosting-lever, is attached to and wound upon the drum 37. The latter has a ratchet-wheel 41, which is engaged by the pawl 42, pivoted upon the frame 35 to prevent the drum from rotating to unwind the hoisting-rope unless disengaged from the pawl. The drum-carrying shaft has been shown as provided with a crank 43, whereby it may be manually operated.

A frame 44, suitably supported upon the base, is provided with bearings for a shaft which is slidable in its bearings and which is slidably connected with a winding-drum 46, which latter is confined against slidable movement between the upright side members of the frame 44. The shaft 45 has been shown as tubular and provided with a slot 47 for the reception of a pin 48, that extends through the drum and serves to connect the latter with the shaft in such a manner as to permit the latter to slide longitudinally. An angular arm or bracket 49, which is slidably a supported in a suitable bearing 50 upon the frame 44, has a bifurcated end 51, engaging an annular groove 52 in the shaft 45, and the other end of said angular member is connected with a shipping-lever 53, fulcrumed at 54 and adapted to be connected by the stop member 55 with any one of several perforations 56 in an arm or bracket 57. The shaft 45 has a clutch member 58, adapted to engage a clutch member 59 upon the shaft 36, carrying the drum 37, and said shafts may thus be coupled or connected together by means of the shipping-lever when the mast is in its operative position, as indicated in Fig. 1 of the drawings. The shafts 36 and 45 may be disconnected by manipulating the ship ping-lever 53, as will be readily understood, and they may likewse be disconnected by operating the foot-lever 18 to throw the stop member 16 out of engagement with the notch 17 in the flange 13 of the sleeve 12, connected with the mast, when the latter may be turned upon its axis, so as to move the dru1ncarrying frame 35 away from the drum-carrying frame 44, thus obviously disconnecting the clutch members upon the proximate ends of the shafts.

Upon the drum 46 is wound a rope or flexible operating member 60, said rope being wound reversely to the winding of the hoisting-rope 39 upon the drum 37. The flexible member 60 is to be connected with draft means, such as a team, whereby it may be unwound from the drum 46, thus serving when the shaft 45 is connected with the shaft 36 to wind the hositing-rope upon the drum 37.

In operation the load-carrying rope is adjusted with relation to the hoisting-lever by means of the cam-lever 23 in a convenient position to enable its free end to be connected with the load that is to be raised. The hoistingrope is unwound from the hoisting-drum until the free end of the hoisting-lever and the short end of the hoisting-beam have been raised and the long end of the hoisting-beam has been lowered to starting position. After the load has been secured the rope 60 is unwound from the drum 46 by draft exercised thereon, thus winding the hoisting-rope upon the drum 37 and elevating the load, as will be readily understood. To swing the load into convenient discharging position, it is only necessary to trip the stop member 16 by means of the foot-lever 18, when the mast will be free to swing upon its axis, the ropes 22 and 33 being guided through the segmental slot in the cap member. While the mast is swung to discharging position the shaft 36 of the winding-drum is obviously disconnected from the shaft 45 of the drum 46; but the hoisting-drum is prevented from rotating reversely by the pawl 42 engaging the ratchet-wheel 41. After the load has been dumped and the mast has been restored to its initial position the pawl 42 is disengaged from the ratchet-wheel 41, thus permitting the hoisting-rope to be unwound from the drum sufficiently to restore 'the hoistingbeam to its initial load-receiving osition, the unwinding of the hoisting-rope Tom the hoisting-drum obviously resulting in the winding of the draft-rope upon the drum 46. By manipulating the shipping-lever 53 the shaft 45 may be unshipped from the shaft 36 of the hoisting-drum, and the latter may then be operated manually by means of the crank 43, provided for the purpose.

When the hoisting apparatus is used in connection with a hay-fork, as shown in Fig. 1 of the drawings, a trip-rope, as 62, will be used for the purpose of discharging the load. This fork, however, is no part of the present invention, and any suitable load-attaching means may be used in connection with the improved hoisting apparatus.

As will be seen from the foregoing description, this improved hoisting apparatus is simple in construction, and itmay be manufactured at a moderate expense. It maybe successfully and usefully employed for a great variety of purposes where it is desired to lift heavy weights or to hoist material of any kind, and the convenience with which the device may be transported from place to place upon the wheels provided for the purpose obviously increases the range of utility of the device to a large extent.
